1.2b - Networking Concepts and Protocols

Flashcards covering key networking concepts and protocols discussed in the lecture.

Content Delivery Network (CDN)

A system designed to provide efficient delivery of data from a central point to end users, often set up regionally.

Virtual Private Network (VPN)

A secure connection method that encrypts data sent over a network to protect it, often using a concentrator for managing connections.

Quality of Service (QoS)

A network management technique that prioritizes certain types of traffic to ensure optimal performance for critical applications.

Time to Live (TTL)

A mechanism that limits the lifespan or hops of a packet in a network, preventing infinite loops and ensuring timely data transfer.

Routing Loop

A situation in networking where packets circulate endlessly between two or more routers due to incorrect routing information.

Cache

A temporary storage area where frequently accessed data is kept to speed up retrieval, often cleared based on a TTL.

Traffic Shaping

A method used by network administrators to control the flow of traffic and ensure high-priority applications receive necessary bandwidth.

Network Concentrator

A device that serves as a central point for VPN connections, optimizing secure data transmission.

High throughput

The capability of a device to process a large amount of data within a given time frame, critical for devices handling many simultaneous connections.

DNS Lookup

The process of querying a DNS server for resolving a domain name into its corresponding IP address.
